TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to a civil engineering detecting apparatus, in particular to energy and mass detecting apparatus for the underground water flow velocity mass point movement, specifically to a three-dimensional flow velocity vector, energy and mass gauge.BACKGROUND OF THE INVENTION[0002]It is known that all the infrastructure constructions of the civil engineering relate to two important influence factors, namely, the interaction of water and rock and soil. The former dynamically and actively etches the foot stone of the underground engineering construction in an ever-present way; the latter statically and passively resists and prevents the etching and damage from the former. A complete and efficient monitoring mechanism should be established in order that both of them realize peaceful coexistence and a long period of stability.

It can find the leakage point quickly and accurately, determine potential safety hazards, and take preventive measures. The invention can track and monitor the space distribution of mineralization, salinity, and volume-weight of water, temperature, and other mass quantitative indexes of the water entity of the flow velocity mass point in real time. It can predict and forecast and takes preventive measures to prevent the occurrence of dam break, wall collapse, and other serious accidents.

Problems solved by technology

To obtain the value in conventional methods, engineers can obtain the leakage characteristics of the individual samples through the indoor leakage experiment mainly by sampling the soil, but cannot acquire the real leakage from the in-situ status.

With the rapid advancement of the modern civil engineering construction, such experiment cannot meet the need of the production practice.

It is known that due to the defect of the “Dupuit pumping experiment theory” itself and the extremely high requirement for the experiment operators, there are fewer and fewer such experiments.

Above all, this experiment only obtains the comprehensive physical property leakage index of each sequence of the rock and soil under the artificial disturbance flow field, namely, the balance amount of rock and soil pore volume and pumping volume, but cannot obtain the leakage velocity field and vector field of the underground water in the natural flow field.

Therefore, it cannot solve many critical technology issues on leakage that the civil engineering meets.

Although the above inventions reach the requirement of measuring the flow velocity and flow direction of the underground water, in the practical application, they relate to the defects and negative effects, such as the influence of radionuclide substances on human body and environment, so that many countries and governments inhibit the use of them or have a conditionally limited use in the strict monitor so that they cannot be promoted and applied in the production practice.

There are issues, such as leakage of reservoir dams, piping leakage of river dams, water-stop structure mass detection of the underground continuous wall bodies, underground water solute transport and diffusion measurement, etc.

In Chinese Patents: single well underground water flow velocity and flow direction and reservoir leakage point measuring method and its device (Application No. 201110295635.5), although it has provided the water flow mass point movement velocity and vector, it cannot check whether substances of the rock-soil body water blocking medium are taken out when the rock-soil body is being driven by the flow velocity vector and energy.
